Bonded NStreme vs. NStreme2

Fri Jul 14, 2006 3:40 pm

What is the advantage of using NStreme2 over bonding two NStreme connections? It would see that the dual NStreme connection would be more flexible in that it your bandwidth can be asymmetrcial vs. symmetrical with NStreme.

Is there a big advantage to NStreme2 I'm missing?

Not that I can see.
One is half duplex and the other is full duplex.
I have a dual nstreme link that's getting 45/45mbps TCP or if I do the BWtester send or receive I get 66mbps TCP.
Seem like if I am getting 66mbps send and reveive then I should get 66/66mbps on both.
Maybe with bonding I could get 132mbps half duplex!

I think that bonding 2 links would be more reliable esp given you coud have channel-polarity diversity. What about bonding 2 nstreme2 links (4 radios)?

what about the fact that you get no redudancy with NStream2 from what i under stand...you loose 1 of 4 antennas or radios you loose the entire link......right?

with bonding you can set it to fail over..

Dual nstream is more "driver related". I had problem with dual nstreaming SR5 and 684HA cards (SR5,HA from one side, and SR5, HA from the other, I didn't have more cards to use 4 equal cards in both PCs :/). Soo I choose bonding 2 nstreams. Problem with the bonding is that one link can get up to 48-50 mbits and the other 60-65 mbits. But bonded together they can reach 95-100 mbits (soo I'm loosing around 15-20 mbits).
I'm not sure about the dual nstream.
But i prefer better way for bonding asymetric links:). (Clasicaly bonding is made for ethernet links I think).

we used this kind of test in some of the MUMs - multiple nstreme2 links were combined to achieve more than 300Mbits

Found This. Gr8. Would two RBs on each side be enough for 100 Mbps?

nope they would not be enought to get 100mbit wirelessly

It doesn't seem like a good idea to use up 8 turbo channels to get that speed. I know it was just a test to see if you could do it. But, in the real world you wouldn't have many channels left to setup and other ptp links or APs.

i think it is completely possible. even one router could do this. we have tested ~60Mbit one direction from one RB500 to another. two wireless cards in each (nstreme2). this means that if you use two such routers on each side, 100Mbits should be no problem.

jo2jo if you have doubts, please explain them.

Thank you Normis, well appreciated.

Now please check my 100 Mbps post .......

A question on this:

- In bonding the main advantage is redundancy, but what about miss-ordered UDP packets like for VoIP applications? Have anybody here experienced that scenario? I mean a bonded link consisting of two wireless links and passing VoIP data.

Thanks
